execute c# code at runtime from code file

Question

I have a WPF C# application that contains a button.

The code of the button click is written in separate text file which will be placed in the applications runtime directory.

I want to execute that code placed in the text file on the click of the button.

Any idea how to do this?

Code sample for executing compiled on fly class method:

using System; using System.Collections.Generic; using System.Text; using System.Diagnostics; using System.IO; using System.Reflection; using System.Net; using Microsoft.CSharp; using System.CodeDom.Compiler;  namespace ConsoleApplication2 {     class Program     {         static void Main(string[] args)         {             string source =             @" namespace Foo {     public class Bar     {         public void SayHello()         {             System.Console.WriteLine(""Hello World"");         }     } }             ";               Dictionary<string, string> providerOptions = new Dictionary<string, string>                 {                     {"CompilerVersion", "v3.5"}                 };             CSharpCodeProvider provider = new CSharpCodeProvider(providerOptions);              CompilerParameters compilerParams = new CompilerParameters                 {GenerateInMemory = true,                  GenerateExecutable = false};              CompilerResults results = provider.CompileAssemblyFromSource(compilerParams, source);              if (results.Errors.Count != 0)                 throw new Exception("Mission failed!");              object o = results.CompiledAssembly.CreateInstance("Foo.Bar");             MethodInfo mi = o.GetType().GetMethod("SayHello");             mi.Invoke(o, null);         }     } }
